Qingtian Stone from Qiantian County of Zhejiang Province is one of the famous "four seal stones" in China. Using such means as thin-section analysis, XRD and SEM/EDX, the authors systematically studied chemical composition and mineral composition of some typical species of Qingtian Stone. Some conclusions have been reached: ① Minerals of the selected samples are mainly composed of microscaly aggregates. ② Four types of Qingtian Stones, namely Fengmenhuang, Huangjinyao, Dengguangdong and Honghuadong, are almost exclusively composed of pyrophyllite, with Honghuadong stone also containing a small amount of ilmenite. ③ Fengmenhei and Zitandong stones are mainly comprised of pyrophyllite and sericite;in addition, Fengmenhei stone also contains a small amount of ilmenite, whereas Zitandong stone also contains hematite. ④ Lanxing, Zhuyoudong and Jiangyoudong stones are composed of pyrophyllite and illite, with Lanxing stone also containing a little illite and cryptocrystalline quartz, and Zhuyoudong stone also containing hematite. ⑤ Zhenzhudong stone is almost exclusively composed of andalusite and pyrophyllite. ⑥ Shanpaolü stone is mainly made up of sericite.
